Percy paid $24.10 for a basketball. The price of the basketball was $22.99. What was the sales tax rate?
Bess [88]
First, determine the difference between the amount Percy paid and the price of the basketball. That is, $24.10 - $22.99 = $1.11. Divide this value by the price of the basketball and multiply the quotient by 100% to get the tax rate. 
                            ($1.11 / $22.99) x 100% = 4.8%
Thus, the sales tax is approximately equal to 4.8%.
